A land vehicle includes a frame structure, a plurality of wheels, and an impact management system. The frame structure includes an operator cage that at least partially defines an operator cabin and a rear compartment positioned rearward of the operator cage in a longitudinal direction. The frame structure includes a pair of rails that each extends in the longitudinal direction from a first end arranged adjacent a pair of front wheels to a second end arranged adjacent a pair of rear wheels. The plurality of wheels are supported by the frame structure. The plurality of wheels includes the pair of front wheels and the pair of rear wheels. The pair of front wheels are positioned forward of the pair of rear wheels in the longitudinal direction.

In some examples, a drive insert comprises a first clip, a second clip, and a retainer. The first clip is configured to be slidable over a first surface adjacent to a first drive slot of a brake disc in a first tangential direction of the brake disc. The second clip is configured to be slidable over a second surface adjacent to a second drive slot of the brake disc in a second tangential direction of the brake disc. The retainer is configured to be slidable over the first clip and the second clip when the first clip and second clip are positioned one the brake disc secure the first and second clips to the brake disc.

A wheel brake arrangement for a wheel of a vehicle, said wheel brake arrangement comprising a wheel hub (102) comprising an outwardly facing gear teeth arrangement (104) arranged in a circumferential direction thereof; and a brake disc (106) comprising an inwardly facing gear teeth arrangement (108) arranged in meshed connection with the outwardly facing gear teeth arrangement of the wheel hub for preventing a relative circumferential movement between the brake disc and the wheel hub, wherein one of the wheel hub and the brake disc comprises a circumferentially arranged groove (110); wherein the wheel brake arrangement further comprises at least one retainer (112) connected between the wheel hub and the brake disc for preventing a relative axial movement between the wheel hub and the brake disc, wherein the at least one retainer is at least partially arranged in the circumferentially arranged groove (110) of one of the wheel hub and the brake disc.

The invention relates to a bar spacer (10) for a braked aircraft wheel, the bar being for fitting to a rim (1) of the wheel in order to drive the rotor disks of the brake in rotation, the spacer being for interposing between the bar and the rim, the spacer comprising two bearing blocks (11) connected together by a core (15) that is pierced to pass a screw for fastening the bar to the rim. According to the invention, the bearing blocks (11) of the spacer include voids defining a void fraction of at least 30% of the volume of the bearing blocks.

A disc brake rotor includes an annular portion having a first surface and a second surface in opposition to the first surface. The first surface and second surface traverse a periodic wave. An inner radial edge of the annular portion traverses an inner periodic wave and an outer radial edge of the annular portion traverses an outer periodic wave. A pattern and a period are the same for the periodic wave, the inner periodic wave, and the outer periodic wave. Thermal radiation elements are coupled to portions of at least one of the inner radial edge and the outer radial edge.

In some examples, a drive insert for a drive slot of a brake disc includes a first insert member configured to cover a first surface of the drive slot, a second insert member configured to cover a second surface of the drive slot, and a bridge member configured to extend between the first insert member and the second insert member. The bridge member is configured to limit movement of the first insert member and the second insert member in a tangential direction of the brake disc when the bridge member extends from the first insert member to the second insert member. In some examples, the bridge member is configured to be in compression between the first insert member and the second insert member.

In some examples, a rotor drive key assembly configured to be positioned on a wheel includes an insert and a rotor drive key. The insert is configured to mate with a wheel boss of the wheel and mechanically connect the rotor drive key with the wheel boss. The rotor drive key is configured to mate with the insert such that the insert limits movement of the rotor drive key relative to the wheel boss in at least a radial direction of the wheel. In some examples, the rotor drive key includes a tab having a tab aperture configured to receive a fastener extending in an axial direction of the wheel and engaging the wheel boss.

In some examples, a drive insert comprises a clip and a retainer. The clip is configured to be slidable over a surface adjacent to a drive slot of a brake disc in a tangential direction of the brake disc. The retainer is configured to be slidable over the clip when the clip is positioned over the surface to secure the clip to the brake disc. In some examples, the clip may comprise a body section and first and second arms extending from the body section. The retainer may comprise first and second legs configured to contact the first arm and the second arm of the clip when the retainer is positioned over the clip. The first and second legs may be resiliently biased to provide an inward clamping force on the clip when the retainer is positioned over the clip.

A clip for a rotor disk of a brake assembly, the clip formed of sheet metal to fit in a slot between, and to, ends of adjacent rotor lugs around the periphery of the rotor disk, wherein the clip is shaped to have a main body portion that is substantially rectangular in form and shaped and sized to fit, in use, onto an inner peripheral surface defined by the slot between the ends of two adjacent lugs, and to extend across the length of the slot from a first main body portion edge to a second opposite main body portion edge; and wherein the clip further comprises first and second end portions that extend from the respective ends of the main body portion at an angle, wherein each end portion comprises an outwardly protruding section and an end clip portion.
